Makes the API for forces and impulses more flexible, easier to
understand and harmonized between 2D and 3D.
Rigid bodies now have 3 sets of methods for forces and impulses:
-apply_impulse() for impulses (one-shot and time independent)
-apply_force() for forces (time dependent) applied for the current step
-add_constant_force() for forces that keeps being applied each step
Also updated the documentation to clarify the different methods and
parameters in rigid body nodes, body direct state and physics servers.
The physics API cannot provide needed functionality to ensure the correct behavior, which might lead to confusion (see `rest_info()`).
However `get_closest_collision_safe/unsafe_fraction()` methods are not removed, because they return correct result from `cast_motion()`.
Reporting rest collision information is needed for move_and_collide and
move_and_slide so floor detection can be done properly, but in the case
of just testing the motion for collision, it makes sense to return false
if the body is able to move all along the path without being stopped.
Updated the logic in test_move and clarified the documentation for
test_move and move_and_collide.
In all physics servers, body_get_direct_state() now silently returns
nullptr when the body has been already freed or is removed from space,
so the client code can detect this state and invalidate the body rid.
In 2D, there is no change in behavior (just no more errors).
In 3D, the Bullet server returned a valid direct body state when the
body was removed from the physics space, but in this case it didn't
make sense to use the information from the body state.
Same as what is already done for shape queries, applied to point and ray
queries. Easier to document and more flexible to add more parameters.
Also expose intersect_point method to script in 3D.
Remove intersect_point_on_canvas in 2D, replaced with a parameter.
NodePath properties are designed to be relative to the given node, so
validity checks are failing in the editor for Polygon2D nodes, which are
relative to the Skeleton2D node rather than the Polygon2D node.
Fixed by saving bone paths as String properties instead of NodePath.
Shouldn't cause a difference for performance since NodePath properties
are technically saved as String anyway.
This crash occurred when an audio stream finished playing in NOTIFICATION_INTERNAL_PROCESS,
during which it would iterate through a loop of playbacks,
leading to a "finished" signal, which removed the audio player from the tree
which led to a NOTIFICATION_EXIT_TREE,
which would mutate the array of playbacks while within the above loop.
This moves the signal callback outside of the loop which avoids the crash.
Note: previously, the signal was called multiple times if the same player finishes multiple times in one frame. Now it is at most once per frame.
Affects AudioStreamPlayer, AudioStreamPlayer2D and AudioStreamPlayer3D
Sets `AlignOperands` to `DontAlign`.
`clang-format` developers seem to mostly care about space-based indentation and
every other version of clang-format breaks the bad mismatch of tabs and spaces
that it seems to use for operand alignment. So it's better without, so that it
respects our two-tabs `ContinuationIndentWidth`.
Damping values are now non-negative.
Add new properties linear_damp_mode and angular_damp_mode to set the way
RigidDynamicBody and PhysicalBone (2D & 3D) use damping values.
It can now be Combine (default) to add to the default/areas, or Replace
to override the value completely (current behavior).
Fix NavigationObstacle3D to be attached to navigation map - without it
the NavigationObstacle3D is not working.
Replace radius approximation algorithm with simple "radius" property.

Change the unreacheable return value of shape_find_owner()
Fix some typoed names from the doc
Add _index to "index" parameters of *_shape_* signals, this is both in doc and in the template. This makes the code, signature and doc easier to understand
Add method to get Node from the _index params of those signals. This was not as easy to find as one would expect. Putting this information where it is needed will help.
Added a parameter in test_body_motion to exclude attached objects from
collision, used to avoid collision with all TileMap tiles with moving
platform motion instead of just the one tile the character touches.
Same changes made in 3D for consistency, and handling potential similar
cases.
-Physics servers test body motion use a class to hold parameters instead
of multiple arguments to make it more readable and flexible since there
are many options
-Improved documentation for test body motion and kinematic collision
-Removed read-only properties for body motion results (not handled in
scripts, so they should be get_ methods only instead)
Shape metadata was only used to get tile information when colliding with
tilemaps. It's not needed anymore since there's an API in tilemap using
body ids instead.
_update_kinematic_motion() shouldn't be called in the constructor
It's too early and causes a first call to set the body position to 0.
Then the second call to set the actual position triggers kinematic
motion, colliding with objects on the path to the initial position.
Side effect of sync to physics now enabled by default.
Allows 2D character controller to work without applying gravity when
touching the ground (also more safely in 3D), and collision detection
is more flexible with different safe margin values.
Character body motion changes in 2D and 3D:
-Recovery only for depth > min contact depth to help with collision
detection consistency (rest info could be lost if recovery was too much)
-Adaptive min contact depth (based on margin) instead of space parameter
Extra CharacterBody changes:
-2D: apply changes made in 3D for stop on slope and floor snap that help
fixing some jittering cases
-3D: fix minor inconsistencies in stop on slope and floor snap logic
In case the reference is stored in script, create a new instance to
avoid overriding the previous values.
Otherwise, re-use the reference as before to avoid extra allocations.
RigidDynamicBody modes are replaced with several properties to make their
usage clearer:
-lock_rotation: disable body's rotation (instead of MODE_LOCKED)
-freeze: no gravity or forces (instead of MODE_STATIC and MODE_KINEMATIC)
-freeze_mode: Static (can be only teleported) or Kinematic (can be animated)
Also renamed MODE_DYNAMIC_LOCKED to MODE_DYNAMIC_LINEAR in the physics
servers.
Changes:
-Added support for custom inertia and center of mass in 3D
-Added support for custom center of mass in 2D
-Calculated center of mass from shapes in 2D (same as in 3D)
-Fixed mass properties calculation with disabled shapes in 2D/3D
-Removed first_integration which is not used in 2D and doesn't seem to
make a lot of sense (prevents omit_force_integration to work during the
first frame)
-Support for custom inertia on different axes for RigidBody3D
Instead of having a physics node named Static that can be either Static
or Kinematic, AnimatableBody is added again as a separate node:
-Inherited from StaticBody to make its usage clearer
-Still separated from CharacterBody to make its usage more focused
Properly implemented constant velocity for kinematic bodies in godot
physics servers (induced velocity without actually moving).
Also updated description for the different physics nodes to make their
usage clearer.
Use a C++ callback instead of Callable for synchronizing physics nodes' state with physics servers.
Remove usage of PhysicsDirectBodyState in physics nodes when not
necessary.
Store PhysicsDirectBodyState for bodies individually instead of a
singleton to avoid issues when accessing direct body state for multiple
bodies.
PhysicsDirectBodyState is initialized only when needed, so it doesn't
have to be created when using the physics server directly.
Move PhysicsDirectBodyState2D and PhysicsDirectBodyState3D to separate
cpp files.
Make separation ray shapes work properly in move_and_slide, wihtout the
specific code in CharacterBody like before.
Now most of the logic is handled inside the physics server. The only
thing that's needed is to use ray shapes only for recovery and ignore
them when performing the motion itself (unless we're snapping or slips
on slope is on).
* Allows calling into native extensions directly with a pointer
* Makes it easier to implement some APIs more efficiently
* Appears with a "*" in the documentation for the argument.
* Implementing the pointer handling is entirely up to the implementation, although the extension API provides some hint.
* AudioStream has been implemented as an example, allowing to create NativeExtension based AudioStreams.
